Same for me. That's a nope on reinstalling everything and syncing 1000+ songs to my poor phone SD card, and losing my sanity entering my Spotify creds into the xbox with a controller. I think I'll go get infuriated by Spotify Connect on my Hifi receiver for a bit.
This is not how it is supposed to work. The music volume can no longer be controlled by either the phone app or on the pc. The music volume cannot be controlled separately via the XSX|X Spotify app either.
Read the problem before saying this is how it works.
We cant let this thread die. There were no reasons for this option to be removed. At leaat let us reduce the volume under 5%. There are alot of game that even at max volume, spotify will completely over power them even at 5%.
